Begonia plant named &#39;PLA0002BEG&#39;

ABSTRACT

A distinct begonia plant named ‘PLA0002BEG’ characterized by its red/purple-eyed leaves. This Begonia is commercially grown for its leaves, its flowers are small and short lasting. The flowers of the parent germplasm grow far above the leaf, in contrast to the flowers of ‘PLA0002BEG’ which grow beneath the leaf’. ‘PLA0002BEG’ grows much more compact and fuller, has much smaller leaves than the parent germplasm, and is homogenous.

BACKGROUND OF THE INVENTION

[0001] The present invention comprises a new and distinct cultivar of begonia plant, botanically known as Begonia conchifolia, and hereinafter referred to by the cultivar name ‘PLA0002BEG’

[0002] The new cultivar was discovered by the inventor, Alfred Nicol Moolenaar in Voorhout, The Netherlands in 1998. The new cultivar was obtained by careful selection from the parent germplasm followed by further evaluations of its characteristics. ‘PLA0002BEG’ is a mutant from the cultivar Begonia conchifolia.

[0003] The new cultivar was first asexually propagated in Voorhout, The Netherlands, in early 1999 by the inventor. Subsequent asexual reproduction of the new cultivar by means of vegetative cuttings has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.

[0004] The new cultivar ‘PLA0002BEG’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly when grown under different conditions of temperature, light intensity and day length without any change in genotype.

BRIEF SUMMARY OF THE INVENTION

[0005] The following characteristics have been repeatedly observed and distinguish begonia ‘PLA0002BEG’ from other begonias commercially known and used in the floriculture industry:

[0006] 1. flowers of ‘PLA0002BEG’ stay below the leaves;

[0007] 2. more compact and fuller growth habit than other known begonia varieties;

[0008] 3. significantly smaller leaves than other known begonia varieties;

[0009] 4. homogenous; and

[0010] 5. striking red/purple-eyed leaves.

[0011] Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘PLA0002BEG’ is the cultivar Begonia conchifolia, an unpatented botanical cultivar. The flowers of the parent germplasm grow far above the leaf in contrast to the flowers of ‘PLA0002BEG’ which stay below the leaves. ‘PLA0002BEG’ has a more compact and fuller growth habit and much smaller leaves the parent germplasm. ‘PLA0002BEG’ is homogenous (stable), whereas the parent germplasm is not.

[0012] The new cultivar ‘PLA0002BEG’ is principally distinguishable from other begonia varieties by compact and full growth habit, small leaves, small flower stems, and striking red/purple-eyed leaves.

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The accompanying photographic drawings of ‘PLA0002BEG’ were taken on Jan. 30, 2001, in Rijswijk, The Netherlands.

[0014] Sheet 1 shows the commercial size and form of ‘PLA0002BEG’.

[0015] Sheet 2 is a close up of the leaf.

[0016] The following observations, measurements and values describe plants grown in Voorhout, the Netherlands under greenhouse conditions which closely approximate those generally used in commercial practice. Color references are made to The Royal Horticultural Society Colour Chart (RHS), except where general colors of ordinary significance are used.
